.Qpplication filed .ianuery 16. 1914. Serial No. 812,571.

To all 2 1 am it may; concern Be it known that I, Hnnmno F. ADIGKES, 511,41 citizen of the United States, residing at Biltin'ore, in the county of Bunconihe and State of North Qsroline, have invented certain new and useful improvements in Binding-Posts, of which the following is =3. speciiieation.

The object of thisinvention is to provide a binding post construction which is especielly adapted to securely hold the wire in electrical contact therewith in cases where the binding post is subjected to constant vibrstion, such as on an automobile or in many other cases where such a structure is desirable.

It is one of the objects of my invention to peripherally groove :1 binding post in such it manner that the ml of a conductor to be connected with. the lsost may he wound or extended therenbout and thereelong in such overlapping relation as to insure a positive electrical contact. I r

A further object of the invention is to connect the free end of the conductor in such anchored relation with the post as to insure retention of the conductor in its wound relation with respect to the post after connection therewith hasbeen made.

Further object of the invention is to provide a. post construction wherein a sleeve insulator may be employed to not only insulete the post but, if desired, to also secure the wire or conductor in the position in which it has been disposed about the post.

Further obiects and features oi the invention will be more fully described in connection with the accompanying drawings and will be more particularly pointed out and ascertained in and by the appended claims. 1

in the drawings, Figure l is a perspective viewof e binding post embodying one form of my invention, and showing the same detached. Fig. 2 a view in elevation thereof showingapplicetion thereto of e sleeve like insulator. Fig. 3 is a sectional view on line 3-43 of Fig. 2. Fig. t is a. perspective view of an improved device for securing the wire in place upon the post. Figl 5 is s nioliifiezl form, of roeens for securing the wire, with parts section and perts in elevation. Fig. is a view similar to Fig. 5 with the post in a slightly different position. Fig. '3 is a. top plan view of the post.

Fig. 'S'is it view in perspective of the-festenaround the post. vlded withe spirally disposed wire-recelv- 80 ing device shown in Figs. 5 and 6, looking at one angle; and, F 1g. 9 is it perspa; ive of the same device looking down thereon.

trically conducting material which is pee5 ripherally grooved in a novel manner to. receive a wire or conductor which is adapted to he wound in place thereon. l ke illustrated, I provide a peripheral wire-receiving groove 2' which is shown to extend from a point near the base of the post longitudinally thereof through to the top 3. Im-

medizitely below the top 3 I provide an annular fastenebreceifing groove 4 which intersects the longitudinal wire-receiving groove 2 end whichis provided with a' wire terminel-receiving recess 5 which extends to the left of the groove 2- a. portion of the way The post 1 is also proof wire employed, I can, as will presently M appear, elweysohtain en efiective electrical contact engagement of the Wire with the wall portions of the grooves in the post.

In applying the conductor to the binding P he wire 8 is'slrinned for here contact 95' with the post, the insulation, terminating at 9. The wire 8 is first extended downs weirdly along and in the longitudinalgroove 2 to the lower point. of intersection; ;l0-

be wound as tightly as its nature will permit to prevent injury. The upper immmel 18 In the preferred form oi? my in It will be understood that the wire can 5 9/ of the spiral groove 6, in the form shown in Fig. 1, intersects the longitudinal groove 2 at its upper end and also the annular fastening groove 4. It will be understood that in first applying the wire to the groove 2, a sufiicient length of terminal end li'will be provided so that when the wire has completed its winds throughout the grooved, it may be disposed under the terminal end 14, as indicated at 15 and there willbe a sufficient length ofterminal end to extend some distance aboutand along in the fastening recess 5.

A fastening-"device is shown in Fig. 4:,-

and indicated at 16, and the same is illustrated in the form of a split ring having a fastening protuberance 11 on its interior at a point substantially opposite the split end 18. The function of the protuberance 17 is to engage the wire lengths at the point (of overwind 15 so as to securely hold the terminal end against slipping into a loose .position so as not to permit the initially taut wire to become loose about the binding post. I provide a cap 19, which may be secured to the top 3 of the post-l in any desirable manner and which is formed of insulating material and provided with an opening 20 through which the wire 8 ex tends outwardly from the post. The post with the wire secured thereabout may be incased by a sleeve 21, of insulating ma- .terial, and the latter may be interiorl-y threaded to engage threads 22 below the grooved portion of the post to secure the sleeve in place. The post itself may be provided with a reduced threaded portion 23 adapted to be turned into any part with which the binding post is to have electrical connection.

In Figs. 5 and 6 I have shown the top of the post provided with a groove 24 having a l-eeess 25 therein which is graduated in size, andavhich, or in other words, the same tapers from a reduced point 26 to a maximum point 27. In this form, the fastening ring 28 is provided with a circumferentially extending protuberance 29 disposed on its interiorand extending thereabout a distance substantially equal to that of the recess 25 so that there will be a wedge lockingor clamping action of the wire between the protuberance 29 and the groove 25. The "terminals" of the split r1ng 28 may be toothed, as indicated at 30, for engagement with wall portions 31 of the.

groove 24:. In order to more effectively anchor the device 28 in position, I may I serrate or roughen the wall 24 of the fastelling groove, as indicated at 32, and if desired, the ring 28 may be likewise serrated although I have found in practice that the serration of either the ring or the groove will be sufiicient to enhance the effectiveness of anchorage. With either the rings 16 or tion, with respect to- Fig. 3, the extreme terminal end would be wedged against the inner wall of the recess 5 and the inner wall of the protuberance 17. It will be seen that if the groove 4i is omitted, with a locking recess 5 extending inwardly from the outer- ,most periphery of the post 1, then the casing 21 itself would wedge the terminal end ll into agroove 5 and the fastening device 16 could be dispensed with.

While I have herein shown and described one specific form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.
